[0028] The clamping assembly is arranged on the top of the base 11 and has two groups. The two groups of clamping assemblies are symmetrically arranged. The clamping assembly includes a clamping plate 12, an adjustment block 13, an axis hole 14 and a receiving groove 15. Two adjustment blocks 13 that can be close to each other are set on the top of the base 11. The clamping plate 12 is rotatably connected to the corresponding adjustment block 13. The two side walls of the clamping plate 12 respectively form a clamping plane and a clamping convex surface. The top of the adjustment block 13 is provided with an axis hole 14 and a receiving groove 15. The base 11 is rotatably connected with a screw rod, and the screw rod and the adjustment The block 13 is threadedly connected, and a motor is fixedly installed on the side wall of the base 11. The end of the screw is fixedly connected to the output shaft of the motor. The two adjustment blocks 13 are driven to approach each other by the screw, and then the two clamping plates 12 drive the corresponding clamping plates 12 to approach each other to clamp the workpiece. One side of the clamping plate 12 is a flat surface, and the other side is a convex arc surface. The clamping plane and the clamping convex surface can be adjusted by rotating the clamping plate 12 to adapt to the workpiece. It has stronger adaptability and higher flexibility for components with curved concave surfaces or regular block-shaped components.

[0029] like Figure 2 、 Figure 3 and Figure 4 As shown, the limiting structure is arranged at the top of the splint 12 for adjusting and locking the position of the splint 12, the limiting structure includes a column 20, a retaining ring 21 and a limiting protrusion 22, the column 20 passes through the shaft hole 14 and is fixedly connected to the adjusting block 13, the splint 12 is rotatably connected to the column 20, the retaining ring 21 is elastically connected to the column 20, the limiting protrusion 22 is fixedly connected to the retaining ring 21, the limiting protrusion 22 is clamped with the splint 12, the limiting structure also includes a plurality of thrust grooves 23, the thrust grooves 23 are opened at the top of the splint 12 and are distributed in a ring array, the limiting protrusion 22 forms a rectangular block structure, the limiting protrusion 22 is adapted to the thrust groove 23, the column 20 forms a cylindrical structure, and the limiting protrusion 22 is fixedly mounted on the retaining ring 21 The lower end face has a radially extending groove on the circumferential surface of the column 20, and the limiting protrusion 22 slides in the groove. In order to lock the position of the splint 12, during operation, the retaining ring 21 can be pushed up first, and the retaining ring 21 drives the limiting protrusion 22 to slide in the groove and squeeze the spring, and the limiting protrusion 22 disengages from the thrust groove 23. After the splint 12 is rotated to adjust its position, the retaining ring 21 is released, and the retaining ring 21 is reset under the action of the spring, and then the limiting protrusion 22 is stuck in the thrust groove 23 at the corresponding position, thereby limiting the splint 12. Multiple thrust grooves 23 make the clamping angle of the splint 12 adjustable, which can not only clamp the space of the plane and the arc concave surface, but also clamp components with inclined side walls, further improving the adaptability of clamping.
